IMPROVEMENT IN GRAIN-DRILLS.

Specification forming part of Letters Patent No. 197,085; dated November13, 1877; application filed July 19, 1877.

To all whom it may concern:

Be it known that I, JAMES S. BOGLE,'Of Springfield, county of Clarke,State of Ohio, have invented certain new and. useful Improvements inGrain-Drills, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, makingpart of this specification ,in which- Figure 1 represents a rearelevation of a section of the grain-box, showing my improvementsapplied. Fig. 2 is a vertical section through the same in line with oneof the distributers, and Fig. 3 is a perspective view of one of theflanged distributor-wheels. and its adjustable gage detached.

Similar letters of reference denote corresponding parts of the machinewherever used.

My invention relates to that class of graindrills employing what istermed a force feed, consisting, in the present instance, of a series ofvertical distributing-wheels, flanged on the periphery, and having thefeed-channel formed inside of said flange, at the side of the wheel, andemploying each an adjustable gage within said channel, for regulatingthe quantity of grain passing through the channel to thedischarge-outlet; and my improvement consists, first, in a novel meansfor effecting the simultaneous and uniform adjustment of the severalgages; and, second, in a novel construction of the distributing-wheels,whereby each is provided with a permanent ledge or templet forregulating the setting of the gage, and thereby securing the arrangementof the several gages in uniform relation to the severaldistributing-wheels.

In the accompanying drawings I have shown only so much of a grain-drillas is necessary to illustrate my improvement, the parts of the machinenot shown being constructed in any usual or preferred manner.

A represents the grain-box B B, the distributer-wheel casin g, securedunderneath said box; and O O, the vertical distributing-wheels, arrangedwithin said casings, and mounted upon a common through-axle, D, by meansof which they are rotated in any usual manner. These wheels are providedeach with a peripherical flange, having the usual inner ribs or starts,and just inside of these starts the disk portion of the wheel has anannular ledge, 0, formed upon it, as shown in Figs. 2 and 3, affording apermanent templet for and insuring the uniform setting of the gages, ashereinafter explained. A

E E are the gages, arranged one in each of the flangeddistributing-wheels, and provided on the side opposite to the wheel witha stud or pivotal pin, 6, which has a bearing in the adjacentcasing-plate. The gage is made in angular form, or is cut away at e, toaccommodate the flange of the wheel, and to permit the shank E of saidgage to pass by and outside of said flange, through a slot or opening atb in the casing-plate, and the outer end of this shank enters aninclined slot, f, formed in a laterally-reciprocating plate, F. (SeeFig. 1.)

A series of the slotted plates F is shown, in the present instanceconforming to the number of distributing-wheels employed, eachadjustably connected with a sliding rod or bar, G, by a sleeve andset-screw, or equivalent device, adapting them to be simultaneously anduniformly adjusted; but other constructions may be employed foreffecting the uniform adjustment of the gages. For example, the inclinedslots, instead of being formed in separate plates adjustably attached tothe sliding rod or bar, as explained, may be formed in the bar itself,expanded in width to accommodate them. The former construction is,however, preferred, as permitting the relative adj ustment of the platesto compensate for any little inaccuracies in the castings or diflerencesin the feed of the different wheels.

The slotted plates F and rod or bar G are arranged and move in a lineparallel with the distributer-wheel shaft, or nearly so, in suitableguide or bearing brackets h at the rear lower corner of the grain-box,thus giving them a compact arrangement, out of the way of the otheroperative parts of the machine; and they are operated by a lever, I,pivoted at 6 upon the rear wall of the grain-box, as shown, or at anyother suitable or convenient point on the machine, as may be preferred.The upper end-of this lever moves over a graduated are or surface, k,and serves, in connection therewith, to indicate the position of thegages, and the amount of seed to be sown per acre, or other givenquantity of ground.

The lever may be held at any desired point of adjustment, by means of aspring-pin entering a notch, by a set-screw attached to the lever andmoving through a slotted are, or by any other suitable device for thepurpose.

In setting the gages E, they are allowed to drop and rest on the ledgeor templet c, in which position they permit the minimum flow ordischarge of seed. The slotted plates F are then adjusted on the rod Gto suit this uniform position of the gages, and are then firmly securedto said rod by the set-screws or equivalent fastening device, asexplained, and thereafter any adjustment of the rod G will efl'ect thesimultaneous and uniform adjustment of the gages, for increasing ordiminishing the amount of seed to be sown per acre, as desired.

The operation of the other parts will be understood without furtherdescription.

The form of gage may be varied to suit the construction of thefeed-wheel employed, the character of the work to be done, or thepreference of the manufacturer, and I therefore do not wish to belimited to any specific form of gage; but

What I claim as new is-- 1. An adjustable pivoted gage arranged andvibrating within the channel of the distributing-wheel, in combinationwith a slide reciprocating in a line a right angles, or thereabout, tothe path of movement of the gage, for adjusting the latter, asdescribed.

2. The sliding rod G, provided with the slot ted plates F, incombination with the adjustable gages E, arranged and working within thechannels of the distributing-wheels, as described.

3. The slotted plates F, combined with and made adjustable on thesliding rod or bar G, for regulating or adjusting the throw of thegages, as described.

4. The pivoted gages E, arranged and made adjustable in the channels ofthe distributingwheels, as described, in combination with the slides F,or their equivalent, and adjusting index-lever I, substantially as andfor the purpose set forth.

5. The adjustable gages E, in combination with the annular ledge ortemplet 0, formed on the distributing-wheel, for effecting the uniformsetting of the gages, as described.
